.. _howto/operator:PythonOperator:

PythonOperator
==============

Use the :class:`~airflow.operators.python_operator.PythonOperator` to execute
Python callables.

.. exampleinclude:: ../../../airflow/example_dags/example_python_operator.py
    :language: python
    :start-after: [START howto_operator_python]
    :end-before: [END howto_operator_python]

Passing in arguments
^^^^^^^^^^^^^^^^^^^^

Use the ``op_args`` and ``op_kwargs`` arguments to pass additional arguments
to the Python callable.

.. exampleinclude:: ../../../airflow/example_dags/example_python_operator.py
    :language: python
    :start-after: [START howto_operator_python_kwargs]
    :end-before: [END howto_operator_python_kwargs]

Templating
^^^^^^^^^^

When you set the ``provide_context`` argument to ``True``, Airflow passes in
an additional set of keyword arguments: one for each of the :doc:`Jinja
template variables <../../macros>` and a ``templates_dict`` argument.

The ``templates_dict`` argument is templated, so each value in the dictionary
is evaluated as a :ref:`Jinja template <jinja-templating>`.
